Marlene Dietrich (German pronunciation: ; 27 December 1901 – 6 May 1992) was a German-born American actress and singer.

Dietrich remained popular throughout her long career by continually re-inventing herself. In 1920s Berlin, she acted on the stage and in silent films. Her performance as Lola-Lola in The Blue Angel, directed by Josef von Sternberg, brought her international fame and a contract with Paramount Pictures in the USA. Hollywood films such as Shanghai Express and Desire capitalised on her glamour and exotic looks, cementing her stardom and making her one of the highest paid actresses of the era. Dietrich became a US citizen in 1939; during World War II, she was a high-profile frontline entertainer. Although she still made occasional films in the post-war years, Dietrich spent most of the 1950s to the 1970s touring the world as a successful show performer.

In 1999 the American Film Institute named Dietrich the ninth greatest female star of all time.
